The answer is 'cooler'. The Cretaceous Period was relatively warm and was experiencing global warming. However, a cooling trend was evident towards the end of the Cretaceous. The Paleocene followed the meteorite impact that resulted in the extinction of most of the dinosaurs. It is thought that dust particles in the atmosphere resulted in cooling during the early Paleocene.
Answer:
Explanation:
The reservoirs are the atmosphere, the terrestrial biosphere (which usually includes freshwater systems and non-living organic material, such as soil carbon), the oceans (which includes dissolved inorganic carbon and living and non-living marine biota), and the sediments (which includes fossil fuels).
Newton proved that the force that causes, for example, an apple to fall toward the ground is the same force that causes the moon to fall around, or orbit, the Earth. This universal force also acts between the Earth and the Sun, or any other star and its satellites. Each attracts the other.
Answer:
When an electric heater is used.
Explanation:
A possible scenario would be the use of an electric heater, where electric power is transformed into thermal energy that will increase the temperature of a room.
The Law of Conservation of Energy states that energy can not be created nor destroyed, it can only be transformed or transferred from one form of energy to another. If we apply this law to our scenario we can appreciate that the electric power is transformed in a different type of energy known as thermal energy.
Answer:
chlorophyll a
Explanation:
This is the pigment s that absorbs light in blue and red light wavelengths when illuminated by sunlight with all wavelength.However it reflects green light. This explains the reason why green plants appears green to our eyes,
the pigments are located in leave and stem of green plant.
Blue light has a wave length of 430nm, while Red wave length is 662nm
